IMPROVEMENT m sl me-sans.

To all whom it may concern:

Be itk'nown that I, UHARLES H. HUDson, of the city,.county, 'andState of New York, have invented a I certain new and useful Improved Spring and I hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon. I I

v The object of myinv'ention is to produce a cheap, light, and efi'cctive spring, which, while peculiarly adapted for use in clothes-wringers and similar articles, may yet be advantageously applied in many other ways,

and to many other articles .,It consists in the combination oftwo or more bars,

-,of wood or other suitable elastic material, with a seat, or hearing, of metal, in which the said rods or bars are firmly set, in such a manner as to allow .one or both. ends of each bar to projectioutwardly a suflicient distance to give, or allow the requisite motion to the spring, ashereinafter more fully set forth. Also, in the peculiar arrangement and construction of the said seat, wherebyit is made light and strong, and the said bars or rods are prevented fi om breaking off at the point where they emergefrom the said seat, while the lattermay be readily taken apart, to replace a broken bar, or for any other purpose, as hereinafter more fully described.

In the accon1panyiug -drawings- Figure l is a top view of a spring constructed according to my invention, and suitable to be'applied to a clothes-wringer.

Figure 2 is a side elevation of the same.

Figure 3 is a side elevation of the same, with. the top plate, which secures the .bars in place,'.removed.

Figure 4 .is an edge view, in detail, of a portion of one of the bars, showing the manner in which they are halved together in the centre, and thus prevented from slipping endwise out of thejgroov'es or channels in the seat A.

-Figure 5 is aside View, in detail, of the same.

Figure dis a side view, in detail, of the topplate, which secures the bars in place. a

, Figure 7 is a sectional elevation, in detail, of another form of seat than that shown in fig. 3, the section being Figure 8 is an'"end view of the seat shown infig. 7.

Figure 9 is; another modification of the seat.

Figures 10 and 11 are still another form of the same.

-A is the seat, or centre-piece, in which the bars B B are snugly fitted, between; the flanges or walls a a and the bearings c c, the latter being curved on their exteriorisoas to' allow the said bars to bend inward,-

without danger of breaking, as clearly seen in fig. 3. The seat Ais formed in two parts, one part, I), being furnished with grooves, or channels, d, and corresponding projecting portions a a and'c 0, into and between which the bars B are received and firmly held; the other part, c, consisting of a plate, shown in fig. 6, which fits over and secures the bars B in position. This plate maybe readily removed at any time, to replace a broken bar, or for any other purpose, by removing the screws which'secure it -to the part b.

In the drawings, the barsB are represented as formed of wood, and are secured from coming out of the seat A, by being halved together in the centre, as shown in figs. 3, 4, and 5.

If metallic bars. are used, they may be bent at a proper angle, and riveted together without crossing, being then secured in the seat in the manner substantially as shown. They may also be made to terminate in the centre of the seat, and secured therein by a key, or a projection on the-bar, made to fit into a corresponding. depression in the seat. The ends of the bars B are curved, so as to slide freely on their bearings without catching. In figs. 7 and 8, a modification in the form of the seat [A is shown, whereby the pressure of the springs in their ,bearin gs is made-to press the partstogether more firmly, instead of thrusting them apait.

The hearings in the centre are made in two parts, one of which, and one ofthe flanges, g, are cast on the plate h, and the other, with the flange i, is cast on the plate j. Screws, 7:, secure the two parts of this seatin place.

In fig. 9 is shown a forin'of the seat, having channels, or grooves, s, formed on its sides, to furnish a bearing for guide posts, on or between which the said seat may be made to; slide as the spring is operated.

Another form of the-same'device isshown in figs. 10 and .11, the amount of metal being much reduced, while leaving the seat almost, if not quite, as strong as in the forms shown in the other figures.-

'- It is obvious thatmany changes in the details of form, construction, and arrangenientof the parts. of

my improved spring may he made,witho1 1t in any wise" departing from the substantial nature and character of the invention. 1. do not, therefore, confine myself to the exact construction shown.

I claim- "1. The combination, with the bars B, of the centrally-located seat A, substantially as and for the purpose set forth;

2.- Forming the outer surfaces of the bearings c 0, against which the bars B hear, of a curved form in the spring, constructed substantially as set forth, as here= inabove described.
